java.lang.ClassCastException: java.util.Arrays$ArrayList cannot be cast to java.util.ArrayList

String[] 转换成 ArrayList 报的错。

String[] str = {"A","B"};
ArrayList<String> list = (ArrayList<String>) Arrays.AsList(str);

解决：再做一次转换，把list 转换成 ArrayList

List<String> list = Arrays.AsList(str);
ArrayList<String> arrayList = new ArrayList<String>(list);
